This custom-made fully bolt-on cross member kit is based on the Pinto-Mustang II independent front IFS suspension system. Adding this kit to your ride eliminates bump steer and other unpleasant surprises resulting in a safe and enjoyable ride. The cross member itself lowers your car about 2-4 inches when compared to stock, and with the adjustable upper coil spring pods there is about 2 1/2″ of additional adjustment possible to further fine tune your setup, providing the best method available to get the correct height geometry. Center support rods provide additional strength to the lower strut rod mount, and the interlocking tabs between upper pods and lower cross member prevent movement to the IFS Suspension system. Use with engine mounting kit CP-2101P

Safety thru Engineering: This fully bolt-on IFS Suspension crossmember uses Pinto-Mustang II based suspension components. Using our 50+ years of expertise and experience, we have engineered this system to provide your classic ride with a suspension that is far superior to that of the original Mustang II in safety, strength, handling and performance.

Interlocking design: The main bolt-on IFS Suspension cross member cradles the frame for superior strength. Adjustment System: Our exclusive ride height adjustment system enables about 2 1/2″ of adjustable height at the coil spring pods, providing the best method for correct ride height geometry or to fine-tune your ride. Note: The adjustment system provides a quick and easy way to correct the driving geometry of your ride. The IFS Suspension cross member itself will lower your ride 2-4 inches from stock. It is important to keep the lower A-arms level. Our adjustment system allows you to set up the suspension correctly and then adjust as needed as the car settles.

Easy and accurate installation: Build using the highest quality standards, our independent front suspension is easy to install. The unique bolt-on system can be mounted safely and securely, and with the included instructions, installation of the IFS Suspension cross member is just a matter of following a couple of steps. The super-accurate fixtures we use when building your cross member ensure a perfect fit.

To fine-tune our ride height adjustment system easily, consider our custom IFS wrench. Set-up rods that temporarily replace the shocks and springs for an easy way to set the correct ride height during the IFS Suspension installation. For use with a small block engine, we recommend using 325lb coil springs with our IFS Suspension, but others are available as well. For use with IF-3540FP Bolt-On IFS for 35-40 Ford.

1. Remove the stock front cross member. Straighten the frame edges and frame lips at where new cross member and strut rod supports will sit. Make sure the frame edges are 90 degrees to side of frame. Remove any rivet heads that may interfere with fit. Grind the rivet heads even with the frame.
2. Bolt the new lower cross member to the bottom of the frame using the original axle rebound rubber hole as a line-up point. The new cross member has matching holes. Steering mounts on the cross member go to the front.
3. Place the coil spring pods over the frame and line them up with the lower cross member. The pods will fit only one way (the taller side goes towards the front). Check for clearances between the frame and the new parts. Correct any interference problems found. At this point we recommend that you check for tire centering. Do this by assembling the upper A-arm and lower A-arm along with a spindle on one side (without a spring) and install a wheel. Visually check for centering. As furnished, the kit is installed 1/2 inch behind the original position. This will center the wheel on most cars. (early 35-36 trucks might differ slightly). In the unlikely event of a miss, the cross member can be moved up to about 1/2 inch without causing issues. Wheel centering is normally not a problem, but it is always better to check.
4. Clamp the upper and lower parts of the cross member together and in place. Again, check fit. When you drill the new holes, do the vertical holes first. Insert the bolts and tighten them. Now drill the side holes (8 total), insert bolts and tighten those as well. The IF-3540FP cross member, frame and pods should now be firmly attached to each other.
5. The strut rod support brackets are next. Straighten the frame edges to 90 degrees (see step 1). Put the strut rod bracket in place around the frame and insert a bolt in the center brace to cross member tube. Now fit the bracket to the frame and locate the point where the bracket fits the frame best. Do this on both sides. Compare measurements, and make them both the same. The strut rod brackets will only fit the frame exactly if the frame is straight and edges of the frame are 90 degrees to the side.
6. Drill the underneath holes first, while keeping the strut rod bracket flush with the outside of the Ford frame. Do the outside holes and the upper holes, bolting them together as you go. To do the upper holes, clamp the flange to the frame and drill through the frame rail and the mount. Check that all bolts are tight.
7. Install components from 1974-1980 Pinto or 1974-1978 Mustang II to complete the installation. Only manual steering is recommended. Use Pinto strut rods, not Mustang II strut rods. Use a new strut rod bushing set. See Ford manual or front end manuals for installation instructions covering the A-arm, strut rods, springs, shocks and line up specs (same as original Mustang II line-up specs). Cut your stock coil to 12″ height (our Chassis Engineering coil springs are already properly sized).
8. We suggest #325 lb coil springs (FS-8325) when using a small block engine and this IFS kit. We have coil springs available in 25 lb. increments. For questions, just give us (or your dealer) a call.
9. To adjust the ride height, first take all weight off the springs. This means jacking the front wheels off the ground and possibly unhooking the shocks. Caution: To prevent injury, be sure to use jack stands to support the car any time you maybe working under it ! Loosen 1/4″ locking set screw and turn height adjuster to new position. The adjustment can be used to lower or raise the car, but is intended to compensate for different springs. For correct geometry, the lower A-arm should be parallel to the ground. Line up groove in threads and re-tighten locking set screw.
10. The final step, after height adjustment is to have the front end aligned to stock Pinto/Mustang II specs. Once a fresh car with a new IFS. gets some good road miles, it may become necessary to adjust the IFS spring pods due to normal settling of the new front coil springs. The lower control arms must maintain a “parallel to the ground” stance for good geometry and prolonged ball joint life. When making such an adjustment, remember to loosen the set screw and add a little anti-seize compound before turning down the spring adjuster. Please note the precision-milled I.F.S. adjustment wrench (IF-0000W). Removing the shock and use of a spring compressor will also aid in this procedure. Re-install shock and tighten set screw.
